Hackers Breach Polish Power Plant Controls via Private Cellular Network, Shutting Down Turbine

A Polish combined heat and power plant experienced a cyberattack where intruders breached its industrial control systems by exploiting a private cellular network used by the local grid operator. This incident, which resulted in the shutdown of a steam turbine and water treatment system, is notable as it represents a novel attack vector observed in a real-world cyberattack, pivoting from a compromised wind-farm network to the plant's controller.
